TIRE OPENING AND HOLDING TOOL;

Specification of Letters Patent. Patnted O t, 19, 1920 Application filedAugust 22, 1919. Serial No. 319,193.

To all whom it may concern Be it known that I, PHILLIP O. SAMPsoN, acitizen of the United States of 'America, residing at Hornell, in thecounty of Steuben and State of New York, have invented certain new anduseful Improvements in Tire Opening and Holding Tools, of which thefollowing is a specification.

The primary object of the invention is to provide a simple tool readilyapplied to a tire shoe or casing for opening the same and holding it inopen position for purposes of examination or for work, such as repairingthe fabric or lining therein.

A further object of the'invention is to hold a tire in open positionwithout the positioning of obstructions within the tire which wouldinterfere with the making of repairs therein and whereby free access tothe injured interior of the tire is made possible for the easy repairthereof.

A still further object of the invention is the provision of an openingtool readily maintained in position by the weight of the tire positionedtherein with the tire arranged upright convenient to the operator formaking repairs within the tire the invention being serviceable forautomobile owners generally as well as tire repairing establishments.

With these general objects in view, my invention consists of a tool thatis easy and inexpensive to manufacture consisting of a plurality ofidentical members as hereinafter fully described in connection with theaccompanying drawing and then claimed.

In the drawing forming a part of this application and in which likereference characters designate corresponding parts throughout theseveral views,

Figure 1 is a perspective View of a tire shoe held upright in openposition by my invention.

Fig. 2 is a perspective view of one set of tools assembled.

Fig. 3 is a erspective view of one of the interchangeab e members of theset, and

Fig. 4 is a perspective view thereof turned in an opposite position.

Referring more in detail to the drawing, my invention broadly consistsof a substantially T-shaped tool or iron 10 having a lever portion 11terminating in a handle 12 at one end of the tool and in a cross head 13at the t D y en posit1on in F 1g. 1 of the drawing. he irons 10 aremounted upon the shoe 17 by posit oning the hooks 16 thereof over theopposite edges or beads 18 of the tire with the levers of the irons 10projecting transversely 1n opposite dlrections beneath the tire in fiatengagement with each other. With the 1rons 10 positioned in this manner,it will be evident that lifting up on the handles 12 w1ll tend to openthe tire 17 by spreading the bead portions 18 thereof a art.

A hollow notch forms a slig it shoulder 19 1n the inner side of each leg14 and is adapted to recelve the adjacent part of the cooperatng toollever thereover, lockin the pair of 1rons l0 together, holding the tlreopen and formm two legs. For further pivoting two of .the irons 10together, a pin 20 may proect from the crotch portion of the iron forreception within a perforation 21 through the lever 11 of the companioniron and whereby two irons may be hung together when looked upon a tire.

It w1ll be evident that two pairs of irons 10, may be placed upon thetire 17 at suitable .dlstances on opposite sides of the point to berepaired, thereby holding the tire open without any obstruction whateverwithin the tire and permitting the insertion of a patch or fabric whilethe tire is not deformed and the patch will retain its shape withoutbuckling when the irons are released for vulcanizing the repairedportion.

The advantages and operation of my invention will be apparent from thisdetailed description thereof, the tire 17 being easily pried open withbut little effort leaving no obstruction in the inside of the tire tointerfere with examination or repair, while the tire is held in anupright position for moving about as may be convenient and the ironsreadily adjust themselves to tires of different sizes.

One iron may be employed for stretching one side of a tire as needed.

What I claim as new is v 1. A tire tool adapted for use in pairscomprising a lever having a narrowed edge portion at its lower side whenin position for use, a handle at one end of the lever, a. head at theopposite end of the lever comprising oppositely projecting curved legand arm portions adapted for positionin at opposite sides of a tire whentwo of t e irons are assembled in tire supporting position with thelevers beneath the tire and the leg portions in their supportingarrangement, thesaid leg portions having shoulders upon their innersides adapted for receiving the narrowed edge ortion of the adjacentcooperating lever t ereover when in use.

2. A pair of tire irons each having a lever adapted for transversearrangement beneath the tire when holding the tire open, a supportingleg projecting in one direction from one end of each lever at oppositesides of the tire, an arm at the opposite side of the lever from the legthereof having a hook at its free end for engaging ove r the adjacentedge of atire when supported'upon the pair of irons and stop means uponeach leg for i the adjacent lever when the device 'is assembled a 3. Apair of interchangeable tire irons each comprising a lever with acrossheadat one end, the said crossheads being adapted for o positepositioning with the levers substantlally in fiat engagement when theirons are in use with a tlre upon said levers between the crossheads,inwardly projecting hooks upon the crossheads adapted for overlying theopposite edgev portions of a tire when mounted upon the ironsandholdingj connections for said irons when in tire supportingarrangement.

In testimony whereof I afiix my signature.

PHILLIP o. SAMPSON.
